7. The Priest (Poltergeist 2)

What's the opposite of fun? A demon priest that sings creepy songs about God and then takes the form of a worm in a bottle of tequila and possesses you until you throw him up in the form of a weird vomit demon? Yeah, no bueno. All these things aren't so bad; it's his smile that throws the creepy-meter needle into the red. The guy sings to kids and hypnotizes them; that alone should set of some warning bells. Anyone who's been to college has met a few vomit-monsters. But when they start singing hymns and trying to kidnap kids while flashing a smile with their 78 front teeth, that's where we draw the line.
